Application filed December 28, 1917. Serial No. 209,225.

To all whom it may concern.

Be it known that I, ALin-ni'r J. Sayers, a

citizen of the United States, residing at Chicago, in the county of Cook and State of dumps and has for one object to provide means for auton'iaticallyclamping the cars in position upon the rails so that they may not leave the rail when the dump is rotated. Another object is to provide means automaticallyresponsive to and operative in coordination with the dumping rotation of the dump itself for locking the caragainst moven'ient which would tend to bring the car wheels out of contact with the rail. Another object' is to provide such locking, means as will automatically adjust themselves to slight variationsii'i height of the car, the diameter-of the wheel and the like so that any car which operates with the dump at all will be firmly and rigidly held in position when it is being dumped. Other objects will appear from time to time in the specification.

My invention is illustrated more or less diagrammatically in the accompanying drawing wherein- Figure 1 is a side elevation;

Fig. 2 is a section along the line ofv Fig. 1.

Like parts are indicated by like characters in the drawings.

A, A represents the tipple track resting upon the ordinary cross ties A A supported from a suitable support by any suitable means not here shown. This'track is interrupted to provide position for the dumping cage which I am about to describe.

A A is a dumping track mounted on the dumping cage in register with the track A, A. This track rests upon cross beams A, A which cross beams in turn areanchored in'the annular frame members A A, one forming either end of the cage. 'lhese members A are bounded by annular tracks ,A which ride upon the supporting wheels A, A", on the shafts A A. The shaft A is continuous to a suitable source of power not here shown,whereby-rotation of the sup porting wheels in engagement with the annular track will cause a rotation of the dumping cage and dump the car.

Any ordinary means may be provided for manipulating and controlling the cage itself, for starting and stopping it, and for driving it, our I have not illustrated these means here as they form no part of my invention and may be of any suitable obvious form. With the parts as shown the car can be run upon the track in the usual manner and dumped in the usual mannerso long as the car is held'in position on the track, and it is the means for holding it on the track which I am about to describe, which form the subject matter of my present applica: tlon.

in shape to conform to the curvature of the dumping cage. It is pivoted as at B on a bracket I5 supported on a longitudinal stay B" extending between the ends of the dump ing cage. This lever 15 extends clear around the cage through an angle of about 180 being everywhere nearer the center of rotation of the cage than the cam roller B except where it is provided with an outwardly bent cam engaging end or member B The arangement is such that'when in the upright position shown in Fig. 2, the lever is rotated in a clockwise position about its pivot point to cause it to lift up on the link B compressing the sprin I T and moving the car engaging hook or flange 13 up out of register and out of engagement with the flange B on the car.

This movement of the master lever B also causes the rotation of anauxiliary locking lever C which is pivoted on the bracket C on a cross men'iber C and extends around to tern'nnate in a loop (7" engaging a link C adapted to compress the sprmg C and lift the hook away from a flange 1 on the opposed side of the mine car. The pin C? mounted in the lever C and engaging aslot C on the lever B causes the lever C1 to To tate in unison with the lever B.

i It will be observed that all that the rotation of this master lever accomplishes while it is engaged by the cam B is to compress the two holding springs and lift them up so that the parts carried by them are disengaged from the car a sufficient distance to make sure that the car will not be contacted by them and will not be interrupted by them as it travels on to the dump. I

have shown the flanges B and C on the car continuous, and the hooks C and C comparatively short. They might be longer,

- and the flanges on the car might be shorter,

end of the excursion is reached the cam engaging part of the lever rides on the cam and the circular looking lever is rotated thus compressing the car supporting springs and 5 it being suflicient that when the car is in the lifting the car holding hooks out of engagedumping position there be a flange or proment with the latch membersor angle bar jcction thereon in register with the spring members on the car body thus leaving, the carried hook.
